$\overline{M}_{0,n}$ is not a Mori Dream Space

Algebraic Geometry 2017-01-18 v3

Abstract

Building on the work of Goto, Nishida and Watanabe on symbolic Rees algebras of monomial primes, we prove that the moduli space of stable rational curves with n punctures is not a Mori Dream Space for n>133. This answers the question of Hu and Keel.
